A baby wagon with improved ease of use has a folding structure which is stably configured, and thus damages to frames, such as twisting or bending of the frames, can be prevented, such that the baby wagon is stably folded and unfolded, the use of the baby wagon is convenient while durability of the baby wagon is excellent, and comfort of a baby can be maintained even when the baby is in the baby wagon for a long time. The frames are manufactured so as to be easily folded even in the state in which the canopy is coupled thereto, whereby the baby wagon is unfolded and folded within a short time, such that that portability and mobility of the baby wagon are excellent, and such that detachment and coupling of a canopy and a wheel assembly are easily performed.

A child stroller apparatus includes a first and a second leg portion, a handle frame having a side segment that is coupled with the first leg portion via a pivot connection, a child seat assembled on the first leg portion, the child seat being slidable along the first leg portion, and a linkage respectively connected with the side segment and the child seat, whereby a sliding movement of the child seat along the first leg portion is linked to a rotation of the handle frame relative to the first leg portion.

A device for transporting children. The transportation device includes a base and sidewalls extending therefrom, forming an interior volume. Wheels extend from a lower side of the base and a foldable seat is affixed to at least one sidewall. A pair of doors are hingedly attached to opposing sidewalls, which allow a child ingress and egress from the transportation device. The folding seat allows the transportation device to include an increased capacity to hold objects when not in use by the child.

A child trailer has a bottom frame and a side frame, and a folding joint is disposed on the tail support of the trailer. A front end of the bottom frame is rotationally connected with a front end of the side frame. A top support rod is fixed at a rear end of the side frame. Left and right ends of the top support rod are respectively connected with an upper-section tail support rod rotating around an axis thereof. A tail end of the upper-section tail support rod is connected with a folding joint. The other end of the folding joint is connected with a lower-section tail support rod. A rear end of the bottom frame is connected with a tail rack rotating around a shaft parallel to the axis of the top support rod.

Proposed is a baby carriage with improved ease of use in which the overall frame structure of the baby carriage is minimized while durability of the baby carriage is maintained, such that it is possible to easily couple a canopy in a state of being separable, it is possible to easily switch between an unfolding mode and a folding mode even in the state in which the canopy is not detached, it is possible to greatly reduce the overall size of the baby carriage in the folding mode, it is possible to easily adjust the angle of a seat back in the form of a chair, and in which a safety bar is located between legs of a baby in the baby carriage, and a tray is easily coupled in a state of being separable such that the baby can eat a light snack.

A child seat detachably installable on a child stroller apparatus includes a seat frame including a first and a second frame portion rotatable relative to each other for unfolding and collapsing the child seat, a side coupling part fixedly connected with the first frame portion and pivotally connected with the second frame portion, a tray connected pivotally with the side coupling part, a tray latch assembled with the side coupling part and operable to engage with the tray for locking the tray in a deployed position for use, and a linking member operatively connected with the tray latch and the second frame portion. A rotation of the second frame portion for collapsing the child seat causes the linking member to move for urging the tray latch to disengage from the tray.

A child stroller apparatus includes a first and a second leg portion, a handle frame, a child seat slidably assembled with the first leg portion, and a linkage. The handle frame has a side segment that is respectively connected pivotally with the first leg portion via a first pivot connection and with the second leg portion via a second pivot connection, the first pivot connection and the second pivot connection respectively defining a first pivot axis and a second pivot axis spaced apart from each other about which the first leg portion and the second leg portion are respectively rotatable relative to the side segment of the handle frame. The linkage is respectively connected with the side segment and the child seat, whereby a sliding movement of the child seat along the first leg portion is linked to a rotation of the handle frame relative to the first leg portion.

A movable carrier includes a bottom frame assembly, a first support member, a link assembly, a position mechanism, and a first unlock member. The first support member has a first end portion pivotally connected to the bottom frame assembly. The link assembly includes a link member and a first connect member. The link member is disposed at a second end portion of the first support member. The first connect member is pivotally connected to the link member and connected to the second end portion through the link member. The position mechanism is disposed on the link assembly and corresponds to the first connect member. The first unlock member is disposed on the link assembly and connected to the position mechanism. When the first unlock member contacts the bottom frame assembly, it carries the position mechanism to move to change the position of the first connect member.

A child trailer has a bottom frame and a side frame, and a folding joint is disposed on the tail support of the trailer. A front end of the bottom frame is rotationally connected with a front end of the side frame. A top support rod is fixed at a rear end of the side frame. Left and right ends of the top support rod are respectively connected with an upper-section tail support rod rotating around an axis thereof. A tail end of the upper-section tail support rod is connected with a folding joint. The other end of the folding joint is connected with a lower-section tail support rod. A rear end of the bottom frame is connected with a tail rack rotating around a shaft parallel to the axis of the top support rod.

The present invention discloses a backrest angle adjusting mechanism including a first support, a second support, a locking member and a reset member. The first and second supports are pivotally connected to each other and are respectively connected to a backrest tube and a stroller frame, and multiple engaging stages are formed between the first and second supports. The locking member is slidably provided between the first and second support, and has a lock position and a release position. The locking member is engaged at any engaging stage when at the lock position; when the driving member moves, the locking member is driven to slide and depart from the engaging stage and becomes located at the release position, thereby implementing angle adjustment of the backrest tube. During a folding process of the stroller frame, automatic folding of the backrest tube can be achieved by folding the frame stroller or by a seat fabric pulling the backrest tube that then moves with the stroller frame, thereby better simplifying operations of angle adjustment of the backrest tube and folding of a baby stroller. The present invention further discloses a baby stroller having the backrest angle adjusting mechanism.
